green screen

That's basic greenscreen technology. As long as your background is the same green color as the box you're holding, it'll key it up with the background and fill it with whatever you want.

So his face magically disappearing as well.....guess I'll pretend not to notice that and remain in awe of technology.

It's not green screen at all. It's projected in real time so people just standing there watching it with their bare eyeballs would also see the 'invisible' effect. The logo is selectively projected on to the object and background to make it appear to vanish.

As for his face not being part of the illusion, the point of the sequence is obviously to show off their logo, so of course they wouldn't put his face in the projection.

Except that this isn't created with chromakey Obviously.

Willing to believe it

That's possible, but from what we're seeing here,but what is making you so sure it's projected? There's no proof of concept, just a showcasing the effect. it could absolutely be simple greenscreen technology. I'm willing to believe there's more to it, but they gotta show something that differenciates it from any greenscreen. If you have a green background and your ball is also the same green, it's going to "dissapear into the background". Watch any weatherman who mistakenly wears a shirt the same color as the background to understand this effect.


After a bit of research, this "X'tal vision' has been apparently out for a while and it's not very clear how it works. Is it live-projected onto the fabric? If yes, that's cool but that has very limited real-world uses.
(Oh let me carry my carefully...

(Oh let me carry my carefully calibrated projector setup. it'll just take 2 hours to setup and then I can be somewhat transparent!)

I'm very curious about this, but "X'tal vision" has just given me forum threads about people discussing the videos, and no real official explanation of any sort.
Please let me know if you find more.

This is oldish tech from pre 2000. From a google search:

"X'tal Vision (CrystalVision) is a projection-based augmented-reality system composed of a projector with a small iris and a retroreflective screen."

The reflective material makes it easier to see what's being projected from the deep depth of field projector.
